Gunbei, Well, I already have a dedicated romex A/C system that's been in place for about a year now and it seems that I'm already star grounded... So all that's left to do is change out the romex for Virtual Dynamics wire... 10 gauge-(short run) and probably 6 gauge armored for the long run-(If my electrician says that it's okay), get some cryoed breakers and I'm good to go. As always, Audiogon has proved to be an invaluble source of knowledge. Best! Stan
